중첩된 양식을 생성할 수 없음:설치

묘사

안녕하세요. 저는 Rails 3.2.6을 사용했습니다. 루비gems와 Repository에서gem을 읽으려고 했지만 "Rails g nested form:install"을 실행할 때 같은 오류가 발생합니다.
다른 분들도 같은 질문이 있으신가요?
도와줘서 고마워요!

감사합니다, 점원!
현재 나의 코드는 다음과 같다.
하지만 파일 입력이 내 테이블에 나타나지 않았습니다 = (
나는 간단한 형식을 썼다.너는 무엇이 잘못되었는지 알아낼 수 있니?
감사합니다!

내부nested_form_for에서 사용 중simple_nested_form_for이지만 fields_for이 필요합니다.

감사합니다!
현재 모든 것이 응답하고 있지만, 폼 =/

토론 #5

을 보일 때 입력 파일이 나타나지 않습니다. 컨트롤러에 첨부 파일을 만들 수 있습니다. 예를 들어 @admin_post.attachments.build.
